Pesticide Poisoning Response

Pesticide exposure can happen during mixing, spraying, cleanup or re-entry. If someone may be poisoned, the right moves are to get to safety, call for help and follow the product label and professionals, not memory.

How does pesticide exposure happen?

Exposure can occur through skin, eyes, breathing or swallowing, during mixing and loading, application, equipment cleaning, spills, drift, and re-entering treated areas. Workers, family members, children and pets can all be affected.

This article does not give treatment or exposure steps. The product label, the safety data sheet, poison control and medical professionals are the authorities, and they differ for each product.

Remember that early signs of exposure can look like other problems, such as a headache, nausea or dizziness. Tell workers that any unusual symptoms after pesticide work should be reported at once and taken seriously.

What should you do if someone may be poisoned?

Call 911 if the person is unconscious, has trouble breathing, has a seizure, or seems very ill. For other exposures, contact poison control or a medical provider right away, and see the official sites for the number. In an emergency, call 911.

Get the person out of the exposure area if it is safe to do so, without putting yourself at risk. Have the product container, label and safety data sheet ready, because responders will ask what the product was. Follow the instructions of the dispatcher and poison control.

Children, pregnant women and people with health conditions can be especially sensitive. Keep them away from mixing, application and treated areas, and ask your doctor about specific concerns.

• Call 911 for serious symptoms.
• Contact poison control for guidance.
• Have the label and safety data sheet ready.
• Do not put yourself at risk.

Why do the label and safety data sheet matter?

The label is the law for pesticide use and contains first aid information, protective requirements and re-entry intervals specific to that product. The safety data sheet adds details for responders. Keep both with each product and where workers can find them quickly.

Do not rely on memory or on advice for a different product. Products differ greatly, and treatment for one may not suit another.

Keep contaminated clothing separate and follow label and official guidance for laundering or disposal, rather than washing it with family laundry.

How can you prepare?

Know how to reach poison control and 911 from where you work, and post the numbers where mixing and loading occur. See the EPA and your state agriculture agency for requirements and training. Many states require training or certification for some pesticide use, and rules vary, so check with your state pesticide regulator.

Make sure workers have training in the language they understand, including how to recognize exposure and whom to tell. Plan for decontamination supplies as the label and official guidance describe, and ensure someone is nearby or checking in when pesticides are mixed or applied.

After an incident, tell your state pesticide agency if required. Reporting rules differ by state, so check with the regulator.

• Post emergency numbers.
• Keep labels and safety data sheets handy.
• Train workers in their language.
• Never work alone with hazardous products.

How can exposure be prevented?

Read and follow the label every time. Use the protective equipment the label requires, and make sure it fits, is maintained and is used correctly. Specific equipment and requirements come from the label and official sources, not from this article.

Store products securely, in original containers, away from children, food, feed and animals. Do not reuse containers for other things. Check weather and wind before application to limit drift. Observe posted re-entry intervals and warn workers and neighbors as required.

Workers' compensation, labor and worker protection rules apply to many operations. Confirm what applies with the EPA, your state agency and the U.S. Department of Labor.

What about long-term health and support?

If you think you may have been exposed repeatedly, talk to your doctor and mention your work. AgriSafe Network provides training for health professionals on farm health. If anyone is struggling, in the US people can call or text 988 for the Suicide & Crisis Lifeline.

Keep a short written list of every product you use, with the active ingredient names from the label, since poison control and clinicians may ask for it.

Where can you learn more?

The EPA pesticides pages explain labels and worker protection, NIOSH and OSHA publish agriculture safety guidance, and your state agriculture agency and extension office offer training and local rules.
